Could low/high humidity levels be the cause? Don't currently have RH meter, they're in FFOF and FFLW mix 2:1 ratio. . . Fed Fox Farm Grow Big through Veg and Fox Farm and Big Bloom during Flower, also in the mix is his high phosphorus bat Guano. Plants are in 5gallon pots

high humidity can cause brown spotting. they get spots then leafs turn yellow and fall off. calmag might help I wouldnt spray anything on flowers especially if you have high humidity. air flow is a good thing do you have any fans?

They're under a 600w hps, I have and AC unit going so temps don get to high and keep a Circular fan running as well

Sometimes leafs build up moisture at dark and it forms little pools like dew. this could be a problem when the lights come on. I used foxfarm stuff once and I had to feed calmag also.

I wouldn't freak out a whole lot about a few yellow fans in week 6 or 8 but it started at week 4 so I have to think its a ph thing or calmag. whats the ph of your water/foxfarm solution?

Are you not using tiger bloom?

Big bloom is not a flower base. It is pretty much a bottled compost tea for ALL stages of growth.

Do the strong dose as recommended on the bottle then cut back like it says. don't water your plants with anything that's not ph adjusted. This is why I grow in my own homemade soil.

Well now I think you may have a CaMg deficiency and possibly a phosphorus deficiency based on the dark spots on the leaves. your supposed to use tiger bloom for flower its your source of N-P-K. Big bloom has almost 0 N-P-K value

nice buds! check the ph of your water after you add the crap and use calmag. make sure that mixture is about 6.4. The soil should be pre buffered and it should balance out so no need to test that.
